As 80s analog synths go the Prophet and the Juno are much better sounding bits of kit...
Yamaha DX7s are what you want for a bit of Eno style spaciness to your music though. Space soundtrack heaven. If you really want to have a mess around with a really inspiring vst synth get the demo of FM8 from Native Instruments. Its a virtual DX7/DX10 clone. In the VST synth world Native Instruments are king.
